, Specification of Letters Patent.

Application filed July 19, 1918. Serial No. 245,742.

all whont it may concern: a Be it known that I, CLAUDE WICKER,

, a citizen of the United States,'and a resi- Jill dent of Memphis, in the county of Selby and State of Tennessee, have invented anew and Improved Cotton-Lint Condenser and Flue, of which the following is a description.

in cotton ginning the cotton or lint is" taken from the saws and blown to aglint flue eitherby an air blast or by a brush revolving at a high rate of'speed and Great passes through a lint due to a condenser.

My invention relates to a novel lint flue and to a novel condenser, an incidental result of the condenser being that the air ex "liausted from the condenser is carried to a I fan; from which it may be dischargedito do useful work as hereinafter referred to.

. lteferenoe is to be had to the accompanying drawings forming a part of this specilica'tion, it being understood that theldraw ingsare merely illustrative of one example of the invention.--

Figure 1 is aplanview largely diagraminatic of ventionr r Fig. 2 is a side elevation thereof;

Fig. l is an enlarged section taken on the an apparatus embodying my inline M, Fig. 1;

Fig. 5 is an enlarged transverse vertical section taken through my improved lint flue that leads from the gin or linter as indicated by the line 55, Fig, 2. V

In the illustrated example, represents conventionally the gins or linters, two' being shown in the present instance, and each discharges the lint to a short lint flue ll hereinafter more particularly referred to, the upper end of the short fine 11 delivering to the main lint flue 12 which is enlarged as at 13 to form a partial casing for a con-- denser designated generally by the numeral la and hereinafter particularly referred to.

is an enlarged section taken on; the I is provided for t e cylinder 29 and its rings 31, the means shownconsisting of sprocket 1 wheels 33 on said rings 31. and driven by From the opposite ends of the condenser,

blow pipes 15 lead, through which the air exhausted from the condenser is drawn by a fin; 16 and discharged from the latter as at r Y Referrin to Fig. 5 it will be seen that the short lint no 11 connects at the'lower. end with the back of the gin or linter 10 and said flue is bellied as at 18 whereby a whirling of the lint is created as indicated by the arrows. A partition 10 adjacent to the inlet of the due 11 divides said flue, the passage 7 20 atone side thereof having an out 21. into which passage any heavy material drawn into the line ll will gravitate as the lint is given the whirling movement. An ad ustable gate 22-iszprovided to regulate the outlet passage 20, said gate being here shown ashinged at its upper end as'at 23 and rovided with a suitable handle. 24. A va vs 11" may be provided in the flue 11 adjacent to the main flue 12," said valve being pivoted at 119. and provided with a weight arm 11. g

The condenser which as a whole is designated 14, includes a suitable frame 25 and Disks or heads 26 are provided, held in fixed relation to the frame 25 by any suitable means, there being shown rods 27 extend-- ing throu h'said. heads and bolted to the frame. T e disks 26 present central openings 28 from which the blow pipers 15 lead.

A revolving condensing cylinder 29 of screen material issecured to flanges 30 on rings 31 revolubly sup orted as by resting on rollers 32 (F1 .3). uitable drive means following manner. The screen body of the cylinder 29 revolves between pairs of rollare, there being an'inner roller 38 and an outer roller 39, and approximately 90 distant from the same are inner and. outer rollers 40, 41, as clearly seen in Fig. 3, said a condensing cylinder mounted therein.

, rollers all being rubber-covered to ive a tight sealing action against the cy inder.

' The air seal is completed by a curved-shield 4.5 extendin from one pair of rollers 38,

39 to the ot er pair of rollers 40, 41, and

,held in'fixed position in any suitable inan nor, as by formin end flanges thereon suitablyfastened to t e adjacent fixed heads 26,

the numeral A 6 indicating one of such' flanges in Fi 3. The roller .39 is shown as carried by t e driveshaft 36 and suitable shafts 42, 43, 44 are provided for the rollers 38, 40 and 41, said shafts turning in suitable bearings provided in the heads 26 or other fixed part of the structure. By the described arrangement that portion of the screen cylinder between the respective pairs of rollers will be cut off from the influence of the suction created in the cylinder by the air drawn through the same. The condensing cylinder travels in the direction of the lint arriving from the flue-12 and the lint is carried overthe cylinder and beneath the roller 41 Where it is relieved of the suction action and permitted to drop to the floor or to any suitable receiver (not shown).

The above described apparatus constltutes an automatic lintflue system having various important advantages over the apparatus now employed, among the advantages being that the product discharge from, the con denser is of a higher grade and 'more uniform. The described condenser eliminates to a great extent the dust now incident to plants of this general character, the provision of the auxiliary-flue between the main flue and the gin or linter and so formed and disposed as to cause the gravitational separation of the heavier foreign matter from the lint before passing to the main lint flue contributes materially to the production of a high-grade product in the condenser.

Furthermore, the apparatus can be operated with much less power than systems now in general use and the exhaustv a1r d1s-,

charged from the fan can be directed to a cyclone or back to the linter or n where it may be used for the pur ose of lowing the,

- means to produce suction within claim as new, and desire to secure by Letters Patent:

1. A lint condenser including .a cylindrical screen, means to deliver material to the screen at the exterior, means to produce suction within the screen to cause the lint .to adhere thereto, rollers adjacent to and bearing respectively against the inner and outer peripheries of thescreen to cause the adhering lint to be carried through the roll- "ers, and means'adjacent to the rollers to cut off the entrance of air to the screen, after passing between the rollers, to free the lint from the influence of the suction.

9-. In an apparatus of the class described,

a lint condenser including a revoluble cylindrical screen, adapted to receive lint at the outer peripheral surface thereof, means to produce suction within the screen to cause the lint to adhere thereto, and pairs of .rollers distant from each other, each pair including a. roller adjacent to the inner periphery of the screen and a roller turning adjacent to the outer periphery of the screen, and an air-excluding guard adjacent to the screen extending from one pair of rollers to the other.-

3. In an apparatus of the class described, a lint condenser including a revoluble cylindrical screen, rings on said screen at the ends, fixed heads for said cylinder adjacent to the said rings, and forming with said rings air tight connections, said fixed heads having openings formed therein, means to turn said screen, and suction-producin means leading into said openings said fixe heads.

4. In a lint condenser, a cylindrical rotatable screen, spaced rollers arranged within the screen and adapted to contact with one side thereof at spaced-points, an air excluding guard arranged within the cylindrical screen between the spaced rollers, means to produce suction within the screen to cause the-lint to adhere thereto, and means to supply the lint in proximity to the exterior of the screen.

5. Ina lint condenser, a cylindrical rotatable screen, pairs of rollers spaced fromeach other, the-rollers in each pair engaging the screen upon the inner and outer sides thereof, and air' excluding guard arranged near the screen and extending between one roller of one pair to one roller'of. the other pair, a casing surrounding a portion of the screen and extending from one roller in one pair to one roller in the other pair, and

t e screen.
